COMBINED HA RROW AND CLOD-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 285,644, datedSeptember 25, 1883.

' Application filed 3, 1883. (bio model.)

To all whom/it may concern Be it known that I, SAMUEL MILLER, a citizenof the United States, residing at Moweaqua, in the county of Shelby andState of Illinois, have invented a new and useful Improvementin'Combined Harrows and Olod- Crushers, of which thefollowing is aspecification.

This invention is designed as an improve: ment upon Patent No. 188,379,issued to WV. H. Kuhn and myself. I have found that in use the sectionsmarked D in said patent, made as therein described, oblong rectangularplanks, will very quickly warp, owing to the double action of the sunabove and the dampness of freshly-turned earth below, thus binding onthe pivot-rod E and avoiding their purpose by preventing them fromswinging on the rod, and that the same action frequently cheeks saidplanks and allows the teeth to fall out; and the object of the presentinvention is to overcome these objections and to provide a better way offastening part of the harrowteeth; to which end it consists in theconstruction and combination of parts hereinafter described and claimed,reference being had to the accompanying drawings, in which Figure l is alongitudinal sectional elevation of my combined harrow and clod-crusher.Fig. 2 is a plan view of the same. Fig. 3 is a top View of one of myharrow-frames in detail, and Fig. 4 is a rear end view of the same.

A represents the frame of the harrow, of rectangular form, boltedtogether at the corners, so that the beams may be separated and closelypacked for transportation.

D represents a system of frames, all hung to swing vertically on onecommon rod, E. Each of these frames consists of two parallel bars, 6,hung upon rod E, a diagonal or brace bar, f, and a eross bar, g, allrigidly secured together. The grain of the wood of cross bar 9 runs in adirection at right angles to the sides 6. To the under side of thiscrossmore straps, h, and screw-bolts 2'. These teeth lean forward at anangle of about forty-five degrees, and each tooth is bent to form theupper part into a shank, to rest against the under side or in grooves inthe under side of the crossbar g. The straps h are placed below theseshanks and bound by bolts '5 up to the cross-bar, rigidly holding saidteeth. By this means fewer holes are made in the cross-bar, and theteeth may be readily removed for sharpening. They may also) be twistedto stand leaning sidewise by partly rotating the shank, thus causing theearth to turn to or fronrplants, as may be desired. In the diagonal barf, I place otherteeth, c, leaning forward only a little. Each sectionbeing hung independently of the others, when a clod is caught under anyone section, it raises the main frame and thedriver occupying seat 13.The united weight supported on said raised section tends to crush theclod under it. In case straw, grass, or other obstructions get caught inthe teeth, each section, be ing made up of timbers, is open, permittingeasy access directly to the obstruction to remove the same by pressingit down with a stick while the harrow .drags over it. While the mainweight of the frame will be supported by any one of the sections whichrises above the others, they will, each by its own weight, swing downand continue to work 111 the ground. Individual sections may be removedto adapt the harrow tocultivate between rows of low corn, &c.

The harrow will be provided with any usual means for attaching-a team,such as the chain 0; and the drivers seat B may be attached in any usualmanner to the main frame A.

I am aware that a harrow made in sections somewhat similar to mine isthe subject of Patent No. 201,435, and I do not claim the same as myinvention.

What I claim as my invention isl. The combination, with tl1e 'mai11frame A, provided with a cross-rod, E, of a series I of frames, D,consisting of the side bars, 6, hung upon rod E, the diagonal bar f, andthe cross-bar g, firmly secured to sidefbars, 0, said frames D hangingindependently upon rod E, and teeth 0 and d, fixed to said frames D, asand for the purpose specified.

2. The combination, with a harrow-frame having longitudinal grooves inits under side, as an axis, and fixed at different angles of of bentbarrow-teeth having shanks adapted right or left inclination from alongitudinal 10 to rest in said grooves at any angle, and verticalplane. bodies hanging to the rear from said shanks,

a strap to rest against the under sides of said shanks, and boltspassing'throngh the strap \Vitnesses: and frame, as described, wherebythe body A. J. STEIDLEY, of the tooth may be rotated upon its shank J.O. MILLER S AMUEL MILLER.
